' BRACKET FOR SHORES.

Application filed. March 10, 1927. Serial No. 174,195.

The main objects of this invention are to provide improved means forsecuringtogether two crossed timbers; to provide an improved form ofbracketadapted to be applied to a strut for supporting a cross piece orhead; to provide improved means for securing the head against shiftingrelative to the-strut; and to provide a bracket of this kind which isparticularly adapted to be used in connection with the T-head of a shorefor securing the cross piece to the upright post or strut.

An illustrative embodiment of this invention is shown in theaccompanying drawing, wherein Figure 1 1s a fragmentary side elevationof ashore to which this. invention is applied, part of a mold beingshown in section.

Fig. 2 is a side elevation of the same, taken from the right of Fig. 1,and partly in section for the sake of clearness.

Fig. 3 is an enlarged perspective of the bracket.

Fig. 4 is an enlarged perspective of one of the braces.

The present invention may beapplied to various forms of crossed timbers,but, in the construction shown, it is applied to a T-head for securingtogether the separate members. In the form herein shown, the shorecomprises an upright mount-ed an improved bracket which supports thecross piece. In the form shown, only one cross piece is illustrated but,if desired, severalbrackets may be employed for supporting any desirednumber of stringers one above another and on opposite sides of thestrut.

As illustrated, the shore is used for supporting a mold 1 of temporaryform such.

as is used in the construction of concrete beams, joists and girders.

The shore, to which the invention is applied, comprises an upright postor strut 2 and a cross head 3, both of which are preferably timbers ofstandard sizes as used in construction work.

In the specific form shown, the improved bracket for supporting the headpiece 3 comprises a hollow casting l having a substantially flat bearingplate 5 and a pair of depending side flanges 6, arranged insubstantially parallel spaced relation and connected to an endfiange orbearing plate 7 and an inclined bottom plate 8. With this im- 5 isbraced by the walls 6, 7

post or strut, on which is proved form of bracket, the bearing plate and8, so as to be adapted to sustain a great amount of weight when theinneredges 9 of the walls 6 abut against the side of the post 2.

Formed in the end wall 7, is an aperture 10 for receiving a locking bolt11, which extends transversely through the post 2 for securing thebracket thereto. Formed on the lower inner edge of the bracket, isadepending flange 12, which is flush with the nner edges 9 of the walls6, and which is providedwith an ear 13 forreceiving a nail 14: used asadditional means for securing the bracket to the strut. Formed on theinner edges of the bearing surface 5 and wall 8, are prongs l5 and 16respectively, adapted to bite into the wooden strut. 2, to secure thebracket against accidental settling under the weight of a load.

The width of the bearing plate5 is substantially equal to or slightlygreater than the thickness of the stringer or head piece 3 which itsupports. Pivotally mounted on the bolt 11, is a latch 17,, which isadapted to be swung int-o and out of position for securingthelower endof the piece 3 from moving away from the post 2. The upper end of thetimber 3 is clamped to the post 2 by a U-bolt 18, embracing the post 2and passing through apertures in the timber The usual wing nuts 19 areprovided for the ends of the U-bolt.

To secure the timber 3 against edgewise tilting, a pair of brace plates20 are secured to the lower edge of the timberB in position to engageopposite ends of the bearing plate 5 of the bracket. The braces 20 areprovided with apertures 21 to receive nails or other fastening means 22whereby they are rigidly secured to the lower edge of the timber 3.Upstanding tapered ridges 23 are formed on the braces to bite into thewooden timber 3 to assist in securing the braces 20 againstdisplacement. Formed on the inner edges of the braces 20, are dependingflanges 2 5i adapted to abut against the ends of the bearing plate 5.

V In operation, one or any desired number of the brackets is secured tothe strut 2 in the proper position. After the stringer or cross piece 8has been placed on the bracket, the latch 17 is swung upwardly to clampthe stringer. The wing nuts 19 may then be tightened. To remove thestringer, the wing on said bearing plate and arranged in snbstantiallyparallel spaced relation to each other a depending end flange located onone side ot said bracket and connecting together said Walls and bearingplat I bottom Wall connecting together the lower edges of said sideWalls and inclined With respectto said bearing plate, a'leckii'ig' boltextending through said end flange for securing said bracket to asupporting member, and a latch pivoted on said bolt and movable intoposition to form a stopprojecting beyond said bearing plate. l

2. A bracket for securing together a pair of'crossed timbers, a bearingplate adapted I tobe mounted on one of said timbers in position tosupport the other timber, a pair of brace plates adapted to be mountedon the lower edge of said other timber on respectively opposite sides ofsaid one member in position to coact with respectively opposite sides ofsaid bearing plate, and tapered ridges on said brace plates adapted tobite into said other timbe I 3; A bracket comprising a bearing plate, apair of depending side Walls on said bearing plate arranged insubstantially parallel spaced relation, opposite ends of said bear-.

a depending end flange connecting together said Walls andplate,a.lock1ng bolt extend ing through said end flange for securingsaid bracket to a supporting member, and a, "latch pivoted on said endflange and 1110*- able into position to fol-ma stop projecting I beyondsaid plate. l
